The pic in post #5 indicates that it is the MPI and has the updated Yamaha part number with the "-10". Their internet sales guy probably just grabbed a pic off the yamaha site and doesn't even know there are two different kits.
I've already got a mcx 270 and love it. I think it would be fun to try a 180 kit as well for those less extreme trips. I agree that the MCX 180 kit is the best on the market, but the MPI is much much cheaper (I know! You always get what you pay for.) These kits were $1500 with a snowcheck of a 2012, but what kinds of deals are people finding who didn't snowcheck? MSRP is around $4k on them. PM me some details if you know of any screaming deals.
I'm not interested in kits supporting "Chinese knock off industry"
